Answer:
<h2>RrYy and rryy
</h2>
Explanation:
1. As given; Round seeds (R)  are dominant on wrinkled seeds (r),
Yellow seeds (Y) are dominant on green seeds (g).
 In a testcross, between an unknown genotype and a homozygous recessive with wrinkled and green seeds (rryy).
offspring are:  
Round and yellow are  53; genotype (R_Y_)
round and green are  49;  genotype (R_yy)  
wrinkle and yellow are 44;  genotype (rrY_)
wrinkled and green are  51 ; genotype  (rryy)
Here, the genotype of parents of these offspring would be RrYy and rryy.

I think the correct answer from the choices listed above is the second option. Lysosomes can be compared to the recycling and garbage centers of a city. This can be justified since they <span>digest excess or worn out organelles, food particles, and engulfed viruses or bacteria.</span>
